James Bertram Collip (November 20, 1892 – June 19, 1965) was part of the Toronto group which isolated insulin.
In 1915, at the age of 22, Collip accepted a lecturing position in Edmonton at the University of Alberta Faculty of Medicine, shortly before completing his doctorate studies.
Collip's task was to prepare insulin in a more pure, usable form than Banting and Best had been able to achieve to date.
JamesCollip, the first chairman of the University's biochemistry department, was, in 1925, the first to successfully extract the active principle from the parathyroid glands.
Collip, who initiated the interest in calcium studies at the University, was born in Belleville, Ontario in 1892.
When Collip arrived Banting and his team had only a crude, uncertain pancreatic extract with which to work; in a remarkably short time the University of Alberta biochemist had refined the technique of insulin extraction to such a degree that the extract could be used in the first human patients.
